IF you want to have a specific templates, images and media folders on unix platform and symbolic link allowed is the one that I have give to you (with the addition of the templates that is a new requirement)
Deploy folder = {site_dir} (when using the default JMS multisites directory)
media folder = images
images folder = images/stories
Template folder = {site_dir}/templates
In general the {site_dir} is the directory that you have assigned to your domain, or sub-domain and must be replaced by this value.
So if slave1 correspond to
www.slave1.com domain that is located on your disk on
/home/slave1/public_html
The definition will be
Deploy folder = /home/slave1/public_html
media folder = images
images folder = images/stories
Template folder = /home/slave1/public_html/templates
